Topic: HD cells

Primary sensory cortical areas are characterized by low-level representations of sensory inputs, but whether these representations are stable over a long period of time or whether they are continuously renewed is still unclear. The head-direction (HD) signal is essential for the spatial navigation system. In the cortex, it is processed by the postsubiculum (PoSub). HD cells each fire for a specific direction of the head of the animal in the horizontal plane and constitute a vast majority of PoSub principal neurons. To address the question of representational stability, we used one-photon calci

Primary sensory cortical areas are characterized by low-level representations of sensory inputs, but whether these representations are stable over time or are continuously renewed is unclear. The head-direction (HD) signal is essential for the spatial navigation system, where it has previously been found that place representation is unstable over long periods of time. In the cortex, the HD signal is processed by the postsubiculum (PoSub). HD cells constitute a vast majority of PoSub principal neurons. Each HD cell fires towards a specific direction of the head of the animal in the horizontal p
